Oldfield Park help points don't have display screens which I could never understand when you go to the effort of replacing the previous equipment that these weren't provided. There are stations that have a fraction of the passengers that Oldfield Park has yet have display screens on their help points.
Oh right, the screen help points were funded by local councils apparently - I know the previous help point at Oldfield Park, the silver one, used to announce calling at patterns of services (when it worked), I'd imagine Oldfield Park now has a yellow button(?) on the help point which now fails to do this! No idea whether the yellow button would announce platform changes.
One example of a really poor upgrade is in Cornwall where Camborne did have a silver help point announcing calling patterns and Hayle the next station down the line had a basic help point announcing trains times/destinations only, and Hayle a station with far less users than Camborne got a screen help point installed, where as Camborne got a help point with a yellow button - so technically a downgrade in information provision, as there is no information stating the calling pattern of a train anymore.
